5-(2-Methyl-5-nitrophenyl)-1H-tetrazole
In the title compound, C(8)H(7)N(5)O(2), the benzene ring makes a dihedral angle of 45.7 (2)° with the tetra-zole ring. In the crystal structure, the mol-ecules are linked into a chain running along the a axis by N-H⋯N hydrogen bonds, and the chains are linked through π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.450 (2) Å].

In the title mol-ecule, C(8)H(11)NO(2), the r.m.s. deviation of non-H atoms from their best plane is 0.031 Å. Mol-ecules are connected via a pair of N-H⋯O hydrogen bonds into a centrosymmetric dimer.

In the title compound, C(8)H(7)N(3)O(2)·H(2)O, the 2-methyl-5-nitro-1H-benzimidazole mol-ecule, excluding the methyl H atoms, is approximately planar, with a maximum deviation of 0.137 (1) Å. The crystal structure is stabilized by water mol-ecules via N-H⋯O(water), O(water)-H⋯O and O(water)-H⋯N hydrogen bonds, forming sheets parallel to the (100) plane. A short inter-molecular contact between t...

The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)° between the planes of the five- and six-membered rings. An intra-molecular C-H⋯O hydrogen bond between the attached benzene...
